It Worked on My Machine, but Nobody Could Trigger It — Four Assumptions I Stripped Out of a Cowork Plugin
I bundled four working automation skills into a plugin and shared it. Only one of them ever fired. Here is how I measured skill trigger rate, and the four assumptions — vocabulary, paths, connections, and naming — I had to strip out before it was portable.
The Night a Connector Grew Write Tools, Your Unattended Job Could Quietly Send Something
The moment a connector update quietly adds write tools, a job you run unattended can suddenly send email or delete files. Here is how to build a gate that snapshots a connector's tool surface, diffs it, and stops unapproved writes before they run — drawn from indie development.
Make Your Nightly MCP Connectors' Health Visible — A Lightweight Ledger for Solo Operators
You don't need Enterprise connector observability to see your MCP connectors' error rate and latency. Append one line per tool call, roll it up weekly, and let regressions ring a bell. A working health ledger for anyone running scheduled tasks solo.
The Two Weeks My Web Monitor Said Everything Was Fine — Field Notes on Catching Silent Misses
A competitor monitor built on Cowork and Claude in Chrome can keep reporting no changes while quietly missing them. Here is how I separated fetch success from extraction success and instrumented the silent failures, with the code I actually run.
When Claude Declines a Request on Safety Grounds, What Should an Unattended Pipeline Return?
A third kind of ending that is neither an error nor a normal completion — a safety decline. Here is how to fold it into a pipeline you run unattended, with a classifier and a review-queue design drawn from indie development.
How Many Tasks Fire in the Same Minute — Flattening Cowork Scheduled-Task Collisions from Cron
When Cowork scheduled tasks bunch up at the same time and fight over shared resources, you can expand every cron expression into fire times, count collisions and true concurrency, and shave the peak with a greedy offset that never moves your premium slots. With working code and measured before/after numbers.
Let the Downstream Task Verify the Upstream Actually Ran Today: A Completion Ledger and Dependency Barrier for Unattended Schedulers
Unattended schedulers have no notion of dependencies, so when a morning data-refresh task fails silently, the noon generation task keeps running on yesterday's leftovers. This is a design for recording upstream completion atomically and having downstream assert its preconditions before running, with working TypeScript and lessons from my own operations.
Trusting a Three-Day-Old Mirror: Stopping Unattended Tasks from Acting on a Stale Working Copy
A persistent clone reused for speed quietly drifts from the remote. Read 'has this article been fixed yet?' from an out-of-sync tree and your unattended task duplicates work or 'succeeds' against an old world. Here is a HEAD-match plus writability preflight, with a self-healing re-clone, in bash.
Failing Loud on Stale Inputs: A Freshness Contract for Unattended Pipelines
How to stop a scheduled, unattended pipeline from silently shipping degraded work when its upstream data is empty or stale. We implement a freshness contract in bash that asserts recency, non-emptiness, and provenance, plus two real pitfalls I hit running Cowork scheduled tasks.
When Your Cowork × GitHub MCP Triage Quietly Drifts Each Run — Field Notes on Idempotency and Label Boundaries
Cowork + GitHub MCP issue triage looks perfect on the first run, then quietly breaks when left unattended: duplicate comments, reclassification churn, rate exhaustion. Field notes on idempotent prompts, label-boundary self-audits, and request budgets that keep weekly triage stable.
Logged as success, but it produced nothing — stopping silent failures in Cowork scheduled tasks with end-of-run assertions
A Cowork scheduled task exits 0, yet not a single artifact was produced. Trusting the exit code alone hides this silent failure. Here is how to turn your definition of done into end-of-run assertions that fail loudly with an evidence log.
My Unattended Task Was Overwriting the Previous Day's Log — the Container's date Was Returning UTC
A Cowork scheduled task that wrote date-stamped logs was silently overwriting the prior day's file. The culprit was the container's date returning UTC. Here is how I isolated it and the permanent fix: pin the timezone, append instead of overwrite, and detect the failure.
Stopping an Unattended Writer From Publishing the Same Article Twice
When a Cowork scheduled task generates articles every day, the real danger isn't a crash — it's quietly publishing a piece that overlaps with one from a few days ago. Here is a gate that compares slug similarity and the day's log before publishing, built from a near-miss I caught this morning.
Why Cowork's bash Says 'No Such File' When Finder Shows It Right There
Connect a cloud-synced folder to Cowork and bash sees empty placeholders while cat fails. Here is how on-demand materialization actually works, and the design patterns that keep your automations from silently dropping data.
